A detailed guide on how employment tribunal judges evaluate procedural fairness in dismissal cases in England and Wales, explaining the range of reasonable responses test, key procedural elements, the role of the Acas Code, time limits, and practical implications for employees and employers.
When an employment tribunal assesses a dismissal claim, one of the most important questions is whether the employer acted procedurally fairly before and during the dismissal. Procedural fairness refers to the way decisions are made, including whether the employer followed reasonable processes and treated the employee fairly throughout. Tribunal judges do not simply decide whether they would have dismissed the employee; they evaluate whether the employer acted within a range of reasonable responses in both the procedure and the decision to dismiss. This guide explains how tribunal judges evaluate procedural fairness in dismissal cases, drawing on legislation, case law, recognised tests and standard procedures.
Procedural Fairness in Unfair Dismissal Law
Under section 98(4) of the Employment Rights Act 1996 (ERA 1996), a dismissal is only fair if the employer acted reasonably in treating the reason they relied upon as sufficient to justify dismissal. This requires judges to examine both how the employer reached its decision and whether it followed fair procedures. Tribunals consider a range of factors, including investigations, communications with the employee, opportunities to respond, and adherence to relevant policies. Their task is not to substitute their own view for that of the employer, but rather to decide whether the employer's actions fell within the band (or range) of reasonable responses that a fair employer might adopt in the circumstances.
The Legal Foundation: The “Range of Reasonable Responses” Test
The starting point for most unfair dismissal claims is the range of reasonable responses test, developed in cases such as Iceland Frozen Foods Ltd v Jones and applied in numerous subsequent decisions. Under this approach:
- A tribunal must determine whether the employer's conduct in dismissing the employee fell within a band of responses that a reasonable employer could adopt.
- It is not enough for an employee to show that a different or more lenient decision could have been made; the tribunal must conclude that no reasonable employer would have dismissed in those circumstances for the dismissal to be unfair.
- This test applies both to the procedures adopted and to the ultimate decision to dismiss.
The tribunal's focus is on the employer's conduct at the time the decision was made, based on what the employer reasonably knew. It does not involve hindsight or substitution of the tribunal's own judgment.
Key Elements of Procedural Fairness
Tribunals typically assess a number of core procedural elements when determining whether an employer acted fairly:
Conduct a Reasonable Investigation
Before dismissing an employee, the employer should carry out a reasonable investigation into the alleged conduct or performance issue. A fair investigation involves gathering relevant evidence, interviewing witnesses as appropriate, and making an informed assessment of the facts. Failure to investigate properly or reliance on incomplete evidence can undermine the fairness of the process.
Inform the Employee of the Issues
Procedural fairness requires that the employee be fully informed of the problem that may lead to dismissal. This typically involves communicating the allegations or concerns in writing, providing relevant evidence, and explaining how the disciplinary process will work.
Provide an Opportunity to Respond
The employee must be given a real opportunity to respond to allegations before any decision to dismiss is made. This usually takes place in a formal disciplinary meeting, where the employee can present their explanation, answer questions, and provide supporting information.
Right to Be Accompanied
Where disciplinary action could lead to dismissal, employers should allow the employee to be accompanied by a colleague or a trade union representative at formal meetings. This right is widely recognised in practice and reflected in the Acas Code of Practice on Disciplinary and Grievance Procedures.
Appeal Opportunities
A fair procedure normally contains a right to appeal the dismissal decision. While there is no statutory obligation to provide an appeal process, tribunals often consider whether the absence of an appeal or failure to deal with an appeal reasonably affected the fairness of the overall procedure.
Timeliness and Consistency
Employers should not unduly delay meetings, decisions, or confirmations, and should act consistently with their own disciplinary and dismissal policies. Prompt and consistent application of procedures enhances procedural fairness.
The Acas Code of Practice and Procedural Fairness
Although the Acas Code of Practice on Disciplinary and Grievance Procedures is not legally binding, tribunal judges must take it into account when assessing fairness in proceedings involving discipline or dismissal. The Code sets out minimum standards that employers are expected to follow, such as investigating fairly, informing employees of allegations, and allowing appeal. If an employer fails to follow the Code without reasonable justification, a tribunal may adjust compensation by up to 25%.
Tribunals recognise that the Code's purpose is to promote fairness and transparency. While not every procedural step in the Code will be practicable in all cases (size and resources of the employer are relevant), substantial departure from these standards can weigh heavily against an employer.
The Relationship Between Procedural and Substantive Fairness
Tribunals evaluate procedural and substantive fairness together. Section 98(4) ERA 1996 requires consideration of both the reason for dismissal and the way in which the dismissal was carried out. A procedural flaw does not automatically make a dismissal unfair if the employer has otherwise acted reasonably, but it can tip the overall fairness assessment if it indicates a flawed process.
The courts have acknowledged that not every procedural defect will render dismissal unfair. Tribunals must assess whether the flaw was significant enough to place the decision outside the band of reasonable responses. For example, a minor administrative error may not make dismissal unfair if the overall process was fair and reasonable.
Examples of Procedural Fairness in Practice
Examples help illustrate how tribunals assess procedural fairness:
Thorough Investigation: An employer receives a report of misconduct, carries out a detailed investigation, interviews relevant witnesses, and documents findings before holding a disciplinary meeting. This demonstrates procedural rigour.
Informing and Responding: An employee is given written notice of allegations, sufficient time to prepare a response, and a meeting where they can explain and challenge evidence. This aligns with the Acas Code and supports procedural fairness.
Appeal Without Prejudice: An employer provides an appeal opportunity after dismissal, especially where new evidence emerges. While not always required, this strengthens procedural fairness where offered.
Time Limits and Procedural Questions in Tribunal Claims
Employees challenging procedural fairness must generally bring their claim to a tribunal within three months less one day of dismissal, and must first notify Acas to enter early conciliation. Missing these deadlines can result in a claim being struck out unless exceptional circumstances apply. Time limits and conciliation requirements ensure that procedural fairness questions are considered promptly.
Common Questions about Procedural Fairness
Does a procedural flaw always make a dismissal unfair?
Not always. Tribunals assess whether the flaw is significant and whether the employer's overall conduct falls within the band of reasonable responses. Minor procedural shortcomings may not make dismissal unfair if the substantive reasons and broader process were reasonable.
Can tribunals impose penalties for not following the Acas Code?
Yes. Failure to follow the Acas Code may lead to an increase or decrease in compensation by up to 25% at the tribunal's discretion.
Is an appeal always required?
There is no statutory appeal right, but tribunals consider the absence or inadequacy of an appeal process as part of the overall fairness evaluation.
Key Takeaways
Employment tribunal judges evaluate procedural fairness in dismissal cases by analysing whether the employer acted within a range of reasonable responses in both the process and substance of the dismissal. Judges consider whether a fair investigation was carried out, whether the employee was informed and given an opportunity to respond, and whether established policies and the Acas Code were applied reasonably. The test is not whether a tribunal would have dismissed in the same way, but whether the dismissal and the procedure leading to it were reasonable in all the circumstances. Procedural failures can influence the fairness assessment and compensation awards, especially where they are significant or persistent.
